SPECIFICATION forming part of Letters Patent No. 301,382, dated July l, 1884.

l l Application led February 1S, 1884. (No model.)

To @ZZ whom, it may concer-72,:

Be it known that I, (Ennemis A. McELnoY, a citizen of the United States, and a resident of Delaware, in the county of Delaware and State of Ohio, have invented certain new and useful Improvements in Cultivators; and I' do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same,

`reference being had tothe accompanying drawings, which form a part of this specifivators in which are combined a sulky-plow and an adjustable harrow; and itconsists in the improved construction and combination of parts of the same, as will be hereinafter more fully described and. claimed.

In the accompanying drawings, A repre sents the plow proper of the ina-chine, which is of ordinary construction, and which is piv.- otally secured at about the center of its standard ,B to the central double crank of the axle C, upon the extremities of which are journaled the main wheels D. -Eindicates the-arch ofthe sulky-frame,upon the top of whiehis securedthe drivers seat- E.

To that side of the arch E which is to the left hand of the. driver is rigidly secured a horizontal beam, F, upon one side of which is secured a segmental rack, G, while to the axle C, between the left-hand main wheel and that side of the arch, is rigidly secured the lower end of a lever, H, the upwardly-entending free end of which is adaptedl to engage with the segmental rack G.

I represents the harrow proper, which is provided with the kdownwardly projecting teeth I', and is loosely connected to the rear cross-piece of the frame .I by means of links I, for the purpose hereinafter set forth. The side pieces of the frameJ have their forward idly'secured the lower end of an upwardly-extending rod, K, the upper extremity of which passes above the horizontal beam F, and is `pivotally secured to the rear end of a lever,

L, pivoted in a suitable bearing, L', on the top of the beam F, and provided at its forward free end with a spring-catch, M, adapted to engage with the teeth of a rack, N, secured in a vertical position upon the beam F.

Upon the rear endof the horizontal beam F is secured a keeper, O, which serves as aguide for the vertical sliding rod K.

To the lower left-hand corner of the frame J are rigidly secured by one of their ends two spring-arms, N N', lthe free extremities of which bear upon the central chatting-plate,

N, of the barrow I, and'thereby serve to hold it down to its work, at the same time being possessed 'of sufficient elasticity to admit ofthe barrow standing at the same inclination to the ground being operated upon,to whatever point the frame J may be raised or lowered by the operating-lever L. A metal rod or bail, O', secured upon the upper side of the hai-row, and beneath which the free ends of the springarms N extend, serves to prevent theharrow from falling when the framed is raised, as would otherwise be the case.

To the lower right-hand corner of the frame J isadj ustably secured a small wheel,X,which serves to decrease the friction of the barrow attachment when the machine is in use.

From the foregoing description, taken in connection with the accompanying drawings, the construction of my improved cultivator will readily be understood without requiring further explanation. It will be seen that by means of the lever H the crankaxle C can be turned so as to increase or lessen the depth of the furrow cut by the plow A,while by means of the lever L the frame .I can be raised or lowered, as desired., to adj ustthe depth to which the teeth of theharrow I will penetrate the ground.

Having thus described my invention,` I claim and desire to secure by Letters Patent of the United States- In a cultivatorof the described construction, the combination, with the sulkyplow herein IOO andarranged to operate, substantially in the manner and for the purpose shown and described.

In testimony that I claim the foregoing as shown and described, of the horizontal beam F, having secured upon ita vertieal mok, N7 operatingdever L, pivoted upon the benin F, and provided at its free end with e Spring- 5 catch, M, adapted to engage with the teeth of `l my own Ihzive hereunto ztfxed my signature the rack N, frame J, provided With the Wheel i in presence of two witnesses.

MQ and spring-arms IN N, and herroW I,

provided With the teeth I, @baffling-plate N,

and hail O', beneath which the free ends of ro the spring-arms N N extend, ell constructed CHARLES A. MCELROY. Vitnesses:
